Katie may be Suri's mama, but she's actively engaged in teaching her little one to ride a bike. Mentoring someone and volunteering have both been linked to good health. According to the Corporation for National and Community Service, research has shown that lending a hand benefits the lender as much as it does the lendee: those who volunteer have lower mortality rates, greater functional ability, and lower rates of depression later in life than those who do not volunteer or mentor. And a survey by the National Center for Volunteering in the United Kingdom, found that people who volunteer report increased self-confidence, social bonding, direction and meaning in their lives, plus a sense of achievement.

Or if you can't get around to mentoring someone anytime soon, take another good-for-your-health clue from Suri and Katie: just hop on a bike!

Are you a mentor to anyone? And when did you learn how to ride a bike?
